Description


This Median barrier has been designed and tested to meet the evaluation criteria of MASH Test Level 3 for a longitudinal barrier. This is the current state of the art performance criteria, exceeding the requirements of NCHRP 350 Test Level 3.

The Sentry Median Barrier W Beam System – Longitudinal System has a conventional ‘C’ shaped post but is shorter, smaller and lighter than public domain versions.

Providing large flexibility and tolerance in system height to accommodate easy transitioning.

  • MASH Test Level 3 compliant as a permanent Longitudinal Median Barrier system
  • AS3845:2015 compliant and recommended for acceptance by the Austroads Safety Barrier Assessment Panel
  • Lesser components, weight and footprint than conventional public domain guardrail systems
  • Superior dynamic deflection results compared to public domain systems
  • No block out, stiffener or bracket between rail and post connection
  • Designed for use with an X-Tensional 350 Median End Terminal
